Expert Q&A
Q: When should I choose single-cut vs double-cut?
A: Single-cut excels in hard materials (HRC>45) while double-cut provides better finish in softer materials.
Q: What's special about your aluminum-cut burrs?
A: Our aluminum-specific design features wider flute spacing and polished surfaces to prevent material buildup.
Q: Can these burrs be used on CNC machines?
A: Absolutely. All our SC shape burrs are balanced for CNC applications up to 35,000 RPM.
Q: Do you offer custom diameters?
A: Yes, we can manufacture custom diameters from 2mm to 25mm with 0.1mm increments.
Q: What's your quality guarantee?
A: We offer 12-month warranty against manufacturing defects with proper use.
